Joint meeting of the chemical To select the appropriate AK UF for each POD, the POD is rounded down to the nearest value in the oral dose column (i.e., values within the same order of magnitude are used). As discussed above, low confidence is placed on the mouse PBPK model. Until a PBPK model has been developed based on mouse data, the use of rat AK UF values for mice is recommended (Summit Toxicology, 2015).

Nevertheless, little is known of the potential for PFOS biodegrdn., even though the importance of characterizing the function and activity of microbial populations detected in the environment was discussed. Perfluorooctanoate (PFOA) and perfluorooctanesulfonate (PFOS) are synthetically produced chemicals, which are used in a range of industries and consumer products as surfactants, due to their water- and oil-resistant properties.
